Frequently Asked Questions

How random are the generated numbers?
The numbers are generated using JavaScript's Math.random() function, which provides pseudo-random numbers. For most purposes, this provides sufficient randomness. For cryptographic purposes, use specialized tools.
Can I generate negative numbers?
Yes, simply set a negative minimum value. The tool works with any integer range, including negative numbers.
What happens if I request more unique numbers than the range allows?
The tool will alert you that it's impossible to generate that many unique numbers from the specified range. Reduce the count or increase the range.
Can I generate decimal numbers?
Currently, the tool generates integers only. For decimal numbers, you can generate integers and divide by an appropriate factor, or use a calculator for precise decimal generation.
Is there a limit to how many numbers I can generate?
You can generate up to 100 numbers at once. For larger batches, generate multiple sets and combine them.
